my ebay page keeps resizing wider

When I load 'my ebay' page logged into ebay, the page continues to resize wider (a mulititude of page widths, 10/20/30 and continues to widen) until the fonts are microscopic. I can zoom in, but the page is effectively unusable.

When I unselect 'auto fit pages' it remains readable and zoomable. Which I of course prefer selected for other sites.

Someone else who uses ebay check this page and confirm, and how would a solution be brought about. Would ebay, or google need to write a fix?
